Hybrid Tea rose plant named ‘Hadmoo’

ABSTRACT

A new and distinct rose cultivar of the Hybrid Tea class characterized by: having stems without prickles; large lavender flowers; flowers borne one to the stem; intense old damask fragrance; rapid repeat bloom; upright bushy plants of medium height.

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.

The cultivar name of this plant is designated as ‘Hadmoo’. It is being marketed under the commercial name of ‘Smooth Moonlight’.

The present invention relates to a new and distinctive cultivar of rose plant of the Hybrid Tea class, which was originated by my crossing ‘Smooth Perfume’ as the seed parent with ‘Blue Boy’ as the pollen parent.

Among the novel characteristics possessed by the new cultivar which distinguish it from:

-   (a) All other cultivars of which I am aware are:     -   (1) Prickles being absent from any stems.     -   (2) Large lavender flower with light pink to red petal edges.     -   (3) Single flower to the stem.     -   (4) Intense old damask fragrance.     -   (5) Very consistent free bloomer. -   (b) Seed parent: Light lavender cluster flowers; no prickles. -    Pollen parent: Low growing; lavender flowers; few prickles.     Asexual reproduction of the new rose cultivar by budding onto the     rootstock ‘Dr. Huey’, as performed at Wasco, Calif., shows that the     aforementioned and all other distinctive characteristics come true     to form and are established and transmitted through succeeding     propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new cultivar, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers such as ‘Yellow Group 16A’ found in Fan 1 of The Royal Horticultural Society Colour Chart.

-   Parentage:     -   -   Seed parent.—IRAR registered: ‘Smooth Perfume’; Class Hybrid             Tea; U.S. Plant Pat. No. 7,728.         -   Pollen parent.—‘Blue Boy’; Class Hybrid Tea; Not patented.

The following observations are made of specimens grown outdoors in Orinda, Contra Costa County, Calif., in the month of October, 2003.
